T-Mobile is once again offering its subscribers a free annual subscription to MLB.TV. This will be the sixth consecutive year that the carrier is offering an MLB annual subscription worth $129.99 for free to its subscribers.

The offer is also applicable for customers who were on the Sprint network but recently migrated to T-Mobile's network. Metro customers are also eligible for this promotional offer.

Stream Out-of-Market Baseball Games on Demand

T-Mobile's announcement comes just a few days before the baseball season is going to start in the US. With an MLB.TV subscription, you will be able to enjoy all out-of-market baseball games barring the ones telecasted on ESPN, FOX, and MLB networks.

With an MLB.TV subscription, you will be able to watch out-of-market games of any team that you follow. Key game metrics like game stats, league scores, and player data will also be available. Additionally, you'll also gain access to documents and World Series films.
